Repair and replacement of the sieve of the powder machine: the sieve is made of steel sheet or iron bar. When the screen is damaged or penetrated by debris, if the damage is small, it can be repaired by riveting or welding; if it is damaged in a large area, it should be replaced with a new screen. When installing the screen, the side of the screen with burrs should be flushed in, and the bright side should be flushed out, and the screen and the screen frame should be tightly fitted. When the ring screen is installed, the stubble in the connecting inner layer should be along the rotation angle to avoid the material being stuck at the connecting point.

Replacement of claws and hammers: Among the crushing components, the crushing claws and hammers are consumables in the food grinder, and they are also specific components that interfere with the crushing quality and output rate. After the crushing claws and hammers are damaged, they should be replaced. Replace now. When replacing the claws of the claw crusher, the disc should be pulled out first. Before pulling out, you need to open the cylindrical pin lock cap on the back of the disk, twist the cylindrical pin with a hook-shaped wrench, and then pull out the disk with a special puller. In order to ensure the smooth operation of the rotor, attention should be paid to the replacement of the entire set when changing teeth, and a static balance test should be done after completion to make the crusher run smoothly. When installing the claws, be sure to tighten the nut, and pay attention to the necessity of loading the spring washer. When changing teeth, the standard parts should be used, and the total weight difference of one tooth claw should not exceed 1.0-1.5 grams. Some of the hammers of the hammer crusher are symmetrical. When the edges and corners of the hammers are blunt, they can be used with variable angles on the back; if one side and two corners have already been damaged, they should be turned around. When changing the angle or turning around, all the hammers should be developed together. After the four sides of the hammers are damaged, they should all be replaced, and pay attention to the total weight difference of each group of hammers should not be greater than 5 grams; spindle bearings, discs, marking sleeves, pins, After the hammer is installed, a static balance test should be done to keep the rotor stable and avoid equipment vibration.

Lubrication and replacement of roller bearings: After every 300 hours of operation of the crusher, the roller bearings should be flushed. If the roller bearing is lubricated by oil, it is advisable to fill 1/3 of the bearing clearance when changing the oil, and the maximum is not more than 1/2. Before working, you only need to tighten the oil cup cover with a small amount. When the roller bearing of the food grinder is obviously damaged or damaged, it should be replaced immediately, and attention should be paid to enhancing lubrication; if the tapered roller bearing is used, the radial distance of the roller bearing should be checked and kept at 0.2-0.4mm. If there is any discomfort, it can be adjusted by adjusting the pad at the roller bearing cover.
